Photographer's Note

To me the subway service of NY city is really good. I bought the week pass, for 29 dolar which allows you take take the number you want subways that period.

About Station and concourse
Many stations have mezzanines. These allow for passengers to enter from multiple entrances and proceed to the correct platform without having to cross the street before entering. They also allow for crossover between the uptown and downtown platforms.
Passengers enter a subway station through stairs towards station booths and vending machines to buy their fare, which is currently stored in a MetroCard. After swiping the card at a turnstile, customers continue to the platforms. Some subway lines in northern Manhattan and the other boroughs have elevated tracks to which passengers climb up to the platforms and station houses via stairs, escalators, or elevators.

Artwork
Many stations are decorated with intricate ceramic tile work, some of it dating back to 1904 when the subway first opened. The subway tile artwork tradition continues today.
The "Arts for Transit" program oversees art in the subway system. Permanent installations, such as sculpture, mosaics, and murals; photographs displayed in lightboxes encourage people to use mass transit. In addition, commissioned art displayed in stations and "art cards", some displaying poetry, are in many of the trains themselves in unused advertisement fixture slots.
